"So hard finding a name that was fun somewhat playful and available. So for now it will be @justdemi. It could grow on me!" she tweeted. "Thanks everyone for your help in finding my new name!"

Moore had previously defended her decision not to change her handle. "Changing my Twitter name isn't a top priority right now," she tweeted shortly after their split. "Sorry it bothers so many of you. Should I not tweet until I do? Does it really matter?"

Moore and Kutcher confirmed their split in November. Since then, Moore had been relatively quiet on Twitter after entering rehab, but she has recently been promoting Lifetime's The Conversation, on which she serves as executive producer.
